PLOW.

SPECIFICATION forming part of Letters Patent No. 449,831, dated March31, 1891. Application filed November 20| 1890. Serial No. 372,083. (Nomodel.)v

be a full, clear, and exact description of the,

My invention relates to an improved construction forplows; and itconsists in providlng the plow with a jointed beam, a means for turningthe beam to one side or the other and maintaining a draft directly uponthe point ofthe plow, to whichever side it may be turned.

In the accompanying drawings I give a more complete explanation of myinvention. Figure l is a plan or top view. Fig. 2 is a side elevation.

A is the rear portion of the beam of the plow, to which the handles B,the standard C, and the plow D are attached in the usual manner.

At the point E thefront portion F of the plow-beam is pivoted by meansof a vertical pivot-bolt G, so that this front portion may be turnedfrom one side to the other.

l'I H are jointed rods or links, the front ends of which are connectedto the stout eyebolts I, which are fixed upon the front end of the beam.The rear ends of these links or rods, extending back one on each side ofthe plowbeam, are connected with a lever K, which is pivoted centrallybeneath the rear and fixed portion A of the plow-beam. One end of thislever is extended out so as to form a pawl or catch, as at K', and thisis engaged bya curved notched rack L. This semicircular rack has itsends pivoted to the side of the beam A, so that it may be lifted up todisengage it from the lever-arm K or pressed down to engage this armwhen it has been turned to any point where it is desired to have itremain.

M is a lever fulcrumed to the rear end of the beam A, having one armextending' bcneath t-he curved movable rack L, and the other arm isconnected by a rod O with a lever P, fixed upon onel of the handles B ofthe plow within easy reach of the plowman.

The operation will then be as follows: When the plow-beam is set in astraight line, the le ver K is locked so as to retain itin thatposition, and plowing will then be done in the ordinary manner. If it isdesired to throw the laudside of the plow toward the vines or trees whenplowing in a furrow, itis done by first disengagng the curved rack Lfrom the lever K, which operates the link-rods, and by turning thislever the front end of the plowbeam is thrown around to the right, whichthrows the landside of the plow toward the left of the line of draft,the lever-arm K being then locked in place by dropping the curved rackto engage it. The draft upon the forward end of the plow-beam will pullthrough the right-hand jointed rod, so that the draft will be in astraight line and the pull will come upon this rod. This enables theplowinan to throw the plow as far to the left as may be desired, whileat the same time keeping the horse in the. furrow. If it is desired tothrow the plow in the other direction, it is done by turning the frontend of the beam in the same manner as before described to the left side,and when it is locked in this position the draft will come upon theleft-hand jointed rod in the same manner as described in the firstinstance. By this arrangement the plow is very easily adjusted andcaused to travel nearer to or farther from the lines of the vines ortrees, the horse may travel at any point desired in the furrow, andthedraft will be maintained in a straight line through the medium of therods. By reason of the joints in the rods, which correspond with thejoint in the beam,it will be seen that when the beam is turned to eitherside the rod which is on the outer side willbend at the joint and liearound the outside ot' the beam, while the inner rod will form a cordacross the inside of the curve or angle formed by the beam, and thedraft will act in a straight line and directly upon this rod. Each ofthe rods is screw-threaded at the rear end and fits into the couplingend H which connects it with the lever K, so that by screwing the rodsin to or out of the coupling they maybe shortened or lengthened to givethem the proper tension and length.

Having thus described my invention, what I claim as new, and desire tosecure by Iletters Patent, is- V 1. A plow having the beam jointed sothat the front epd may turn about a vertical axis with relation to therear portion, a lever ful- ICO crunied to `tn rn in a horizontal ,planeiipon therearlportionof the beanniieible con-nections extending from theopposite ends of said lever to corresponding sides of the front andmovable portion of the beam, and a device for holding the lever so thatthe beam may be turned vto eithe'rside and'maintained at an angle withthe rear portion, substantially as herein described.

2. In a plow, the beam having a joint in its length about which thefront portion may be turned from side to side, a lever fulcrumed to therear portion of the beam so as to turn in a horizontal plane,jointed or'liexibleiods having .the front ends connected with oppoysite-"sides of`the liront portion lof 'the plow- "beainfand the rearfends lconnectedWit/licor- 'r'espondin'g e'n'ds of -the'lever,and a l'movable-latchingdevi'ce ad'a'pted to engage'theleverso 'thatvth'e lfron-tend'of thelb'eammay be turned to'eithe'r side by the Amovement"ofthelever *and retained A'an angle with therearlportion,su'bstantiallyfa's herein described.
